LG 50UH5500-UA won't turn on, power LED blinks three times
The TV is not turning on, I opened up the back to look at the boards and nothing is obviously fried. While it’s plugged in I can hear a whine from the powerboard, I assume that’s normal.
ANSWERS:
A blinking LED on lots of devices normally means the device has a known fault of some type. I imagine you’ve googled a solution and tried unplugging overnight then restarting. The main board might flash LED if it’s not getting enough power or if there is a short somewhere.
